Well, you can't accuse Bill Gross of not knowing how to make a splash.

The billionaire bond trader with a penchant for parading around investment conferences in sunglasses and referring to himself in the third person released a note Wednesday morning detailing his outlook for the global economy, and within an hour of its release, Gross' name began trending on Twitter.

While a cursory glance at Gross' note might attribute the attention to his opening line ("Size does matter you know") or even his ruminations on the animal kingdom ("Elephants, giraffes, whales… Who couldn't love them?"), the real reason people are talking about Gross is because of what he had to say about the Federal Reserve and its actions regarding interest rates.

"The timing and the eventual 'size' of the Fed's 'tightening' cycle that I have long advocated now seems to be destined to be labeled 'too little, too late,'" he writes. "The 'too late' refers to the fact that they may have missed their window of opportunity in early 2015, and the 'too little' speaks to my concept of a new neutral policy rate which should be closer to 2% nominal, but now cannot be approached without spooking markets further and creating self-inflicted 'financial instability.'"
